CHECK-ROW CORN-PLANTER.

SPECIFICATION forming part of Letters Patent No. 323,048 dated July 28, 1885.

Application filed June 14, 1884. (No model.)

To all whom it may concern:

Be it known that we, ALFRED LIsToN and WILLIAM H. NAVERT, citizens of the'United States of America, residing at Emerson, in the county of Mills and State of Iowa, have invented certain new and useful Improvements in Check- Bow Corn-Planters; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompaning drawings, and to letters or figures of reference marked thereon, which form apart of this specification.

This invention relates to certain new and useful improvements in check row cornplanters; and it consists in the construction and combinations of parts, as will be hereinafter specifically set forth, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a plan View; Fig. 2, a front view. Figs. 3 and 4 are detail views, and Fig. 5 is a detail perspective view. Fig. 6 is a perspective view of the entire attachment, illustratingthe parts in a different position.

A represents a bar or frame, which is secured across the frame of the corn-planter so as to be adjacent to the seed-slide, and upon this frame are mounted and affixed the operating parts of the check-row mechanism.

To the rear portion of the bar A, near the ends thereof, are secured horizontal and rear wardly-proj ecting brackets A, which serve as a support for the outer pivoted portion of a swinging forked lever and a frame, B, which is attached at the ends of the transverse bar A. The frame B consists of a casting having a body portion, B, from which projects a segmental bearing or guide plate, I), the rear end of which is connected by a transverse bar, I), to the main portion B. The segmental guideway or plate I) is provided at its forward end with a recess or depression, b. The main portion B of the bracket B, attached to the end of the transverse bar A, is provided at its extreme rear end with a curved upwardlyprojecting pin or guide, 0, immediately in front of which is bolted an inclined sheave or block, 0, which is seatedin the recess formed in the raised portion of the rear end of the bar B, the front end of this raised portion forming a stop, 0 against which the swinging forked lever will strike to limit the play thereof. Near the front of the portion B of the frame is formed an upwardly-projecting.

stop, (I, which limits the forward movement of the swinging forked lever. Upon the extreme forward end of the frame B is secured an upwardly-projecting arm, d, which carries at its upper end a horizontally-projecting pulley, d. In rear of the arm and pulley d d is pivoted, between upwardly-projecting shoulders formed on the frame B, a guide pulley or block, D.

The operating-lever E consists of two members, E E, which project substantially at right angles from each other, and at the meetingpoint are provided with a hub, F, which moves upon a pivot which is attached rigidly to and projects upwardly from the bracket A. The pivot-pin upon which the hub operates is provided with a reduced upper portion and a shoulder, f, and the hub F is provided with a recess, f, which corresponds in size with the outer circumference of the lower portion of the pivot-pin. The reduced portion of the pivot-pin is encircled by a spiral spring, F, the upper end of which is secured to the hub F, while the lower portion is secured to the enlarged portion at the base of the pivot-pin. This spring has a tendency to throw and hold the member E of the forked lever against the stop G of the frame B.

The member E of the swinging lever is provided at that portion immediately above the longitudinal bar B of the frame B with a recess, 6, and the end of this member does not project beyond the segmental restb. Adjacent to the hub F the member E is provided with an inclined guide portion, 9, which extends from the upper portion of the hub to the horizontal portion of the member E.

To the end of the member E is pivoted a casting, E, which is capable of a rocking motion upon the end of said member, and carries at its outer end a friction-roller, e, which travels upon the way I). The opposite end of this member or casting E projects over the member E and is raised therefrom to form a horizontal slotH, through which the provided with vertical side wings, h, through which the horizontal pivot-pin passes.

The end of the member E of the swinging lever is formed integral with the hub, and is recessed at its outer end, as shown at z, and is provided with several perforations for the reception of a retaining-pin, i, which passes through the end of a connecting-bar, G.

To the central portion of the transverse supportingframe A is rigidly secured a supporting-plate, I, which is provided with upwardly-proj ecting pins 1 I, upon which operate, respectively, the gear-wheels J J which mesh with each other, as shown. The gearwheel J is provided on its upper face with an annular groove, j, in the base of which are formed inclined depressions j.

From the upper portion of the gear-wheel J projects a pin, is, to which is attached an arm, L, with a hooked end, which engages with a pivoted lever, L, the lower ends of which carry a rod and coupling, which is attached to a reciprocating seed-slide, of ordi nary construction, or bar for operating the same.

The arm G, which is pivoted at one end to the member E of the swinging forked lever, is bent at its opposite end, as shown in Fig. 1, and provided with a downwardly-bent portion, which engages in the annular bent portion j of the gear-wheelJ and engages with the inclined depressions formed therein. The ends of these arms G are held against vertical displacement by a cap, M, which is located immediately above the gear-wheel J, so as to cover the annular groove therein, and is attached to the frame I by means of bolts which pass through a projecting portion immediately between the gear-wheels J J. This cap is cut away at diametrically-opposite points, so as to afford a passage-way for the arms G.

00 represents the wire or cord, which is stretched across the field in the usual manner, and the said cord is provided with tappets an.

The operation of our invention is as follows: The mechanism shown in the accompanying drawings is supported upon the frame of a cornplanter and drawn across the field in the direction indicated by the arrow in Fig. 1, the wires being stretched across the field in the usual manner. The wire passes under the projections c and around pulley 0, located in the end of the frame B, and from thence through the open slotH between the portions E E of the swinging forked lever, and from thence out over the pulley D and under the pulley 01. As the machine is drawn across the field, the tappets upon the wires will come in contact with the slides H and carry the forked levers against the stop d, and when in this position the friction-roller 6 will lie within the recess 1) and allow the portion E of the lever to be depressed, thus opening the slot and allowing the tappet to pass through the same, as shown inFig. 6. This movement of the arm E of the swinging forked lever will effect a quarter-turn of the gear wheel J lever having a recessed hub supported on said pivot and containing a torsional spring attached to said hub and pivot, and a movable portion or casting hinged to one end of said lever and adapted to maintain the tappets in contact with the forked lever until it completes its throw, substantially as set forth.

2. The combination, in a check-row attachment forcorn-planters, of a segmental guide forming part of the operating-frame of the attachment and having a depression at or near one end, a fork-lever pivoted at its elbow and adapted to be operated in one direction by the partial action of a spring, one of the portions of said fork-lever extending adjacent to the segmental guide, and cut away, as specified, and a pivoted portion, b, having one end overlapping the cut-away portion of said fork-lever, and adapted to oscillate vertically on its pivots, and carrying at its outer portion a roller designed to travel upon the segmental guide and enter the depressed portion of the latter to tilt the rear end of the pivoted portion, substantially as set forth.

3. The combination, in a cheek-row attachment for corn-planters, of a segmental guideway, b, forming part of the operating-frame of the attachment and having a depression, I), located at one end thereof, a fork-lever pivoted at its elbow, as described,and having one of its portions extending adjacent to the said segmental guide, and cut away, as specified,and a casting, E"', pivoted on said cut-away portion so as to oscillate vertically on its pivot and overlap the cut-away portion of the lever, the outer end of said casting carrying a roller designed to travel on the guide and enter the depression of the same, the said guide being formed integrally with a support, B, carrying guide-rollers or pulleys and provided with stops 0 and d, substantially as set forth.

4. In a check-row corn-planter, the combinationof the swinging lever located at each side of the machine and each operated in one direction by a tappet-wire and in opposite directions by a spring, each of said levers carrying at one end an arm, G, engaging with a horizontally-grooved ratchet formed in the face of the horizontal rear wheel, which is additionally provided with peripheral teeth to mesh with another wheel provided withmechanism for operating the seed-slide, substantially as shown,and for the purpose set forth.

5. The combination, in a check-row attachment for corn-planters, of a segmental guide forming part of the operating-frame, a forklever located at each side of the machine and having one portion extending adjacent to said guide, and cutaway, as described, a pivoted portion, 13, pivoted on said lever to overlap the cut-away portion thereof, and adapted to oscillate vertically on its pivot, and carrying a roller designed to travel on the guideway and enter the recess thereof at the limit of its movement, and an arm, G, pivoted to the inner end of each fork-lever and engaging at the other end with a central gear-wheel, J ,having formed on its upper face an annular ring, with ratohets, and mechanism for operating the same, substantially as shown, and for the purpose specified.
